Answer is: <span>1 mol CH</span>₄/<span>16,0 g CH</span>₄.
Chemical reaction: CH₄ + 2O₂ → CO₂ + 2H₂O.
m(CH₄) = 50,6g.
M(CH₄) = 16g/mol.
n(CH₄) = m(CH₄) ÷ M(CH₄) = 50,6g ÷16g/mol = 3,16mol.
n(CH₄) : n(CO₂) = 1:1.
nCO₂) = 3,16mol.
m(CO₂) = m(CO₂) · m(CO₂) = 3,16mol · 44g/mol = 139,15g.
M - molar mass.
n - amount of substance.

Frequency of photon = is 6.85 X 10¹⁴ sec⁻¹
Energy of photon , E = hv
where h is Planck's constant, v is the frequency of photon
E = 6.63 × 10⁻³⁴ J.s x 6.85 X 10¹⁴ s⁻¹
E = 4.54 x 10⁻¹⁹ J
Therefore, the energy of a photon of green light is 4.54 x 10⁻¹⁹ J.
- The answer is shorter wavelength and equal speed.
That is, compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have shorter wavelength and equal speed.
This can be seen by the reaction given below:
h= Planck's constant
c=speed of the light
=frquency
=wavelength
So, higher is the frequency, lesser is the volume while speed remains constant as c is speed of light.
